Definitions

  • the invention relates to an electric shaver according to the preamble of claim 1.
  • a shaving head which can be freely pivoted into any pivoting positions and which is associated with an actuating switch which is displaceably mounted on the housing.
  • the actuating switch is operatively connected to a control device which is used to adjust a displaceably mounted actuating element which limits the pivoting movement of the shaving head and engages in the pivoting region of the shaving head and is guided along a curved path.
  • the shaving head can be determined with this control device only after the shaver has been started up, but not in a state in which the shaver is out of operation.
  • an electrically drivable shaving device with a shaving head which is pivotably mounted in side arms of a frame arranged on the housing.
  • a protective cap is placed on it, which has cutouts in its side cheeks that are adapted to the outer contour of the side arms. By putting on the protective cap, the cutouts are positively pushed onto the side arms, so that the shaving head is then secured against pivoting.
  • the object of the invention is to provide an improved electric shaver.
  • the control device works independently of other control devices which are provided for positions of the pivotably mounted shaving head during shaving, ie in the operation of the shaving apparatus.
  • the plunger is equipped with a receiving part, in which a spring is accommodated, which is supported at one end against a fixed part of the shaving apparatus, at the other end against the plunger, and in a certain switch position of the actuating switch, the plunger into one adjusted the shaving head locking position.
  • a spring is accommodated, which is supported at one end against a fixed part of the shaving apparatus, at the other end against the plunger, and in a certain switch position of the actuating switch, the plunger into one adjusted the shaving head locking position.
  • a further curve or Slideway is arranged, which is provided between the upper knife of the razor and the first cam track, and that in the position allowing a pivoting movement of the shaving head, the outer end of the plunger can be brought into contact with the second cam track and dampens the pivoting movement of the shaving head.
  • the plunger head arranged at the outer end of the plunger is arranged on one side of the plunger and the Tappet is received in a recess provided in the housing of the shaving apparatus and extends through a recess of a shaving head carrier belonging to the shaving head.
  • Figure 1 shows an electric shaver with a housing 1 and from the shown central position in opposite directions about a pivot axis Z relative to the housing pivotable shaving head 2, with two short hair cutting systems K1, K2 and a sliding switch 4 arranged on the front 3 of the housing 1 with built-in long hair cutting system L.
  • the shaving head 2 is pivotably mounted relative to the housing 1 and is equipped with an upper knife 36 and a lower knife 31 driven by a motor and assigned to the upper knife 36.
  • the shaving head 2 is freely pivoted between two support arms 5, 6 formed on the housing 1 by means of the bearing elements, not shown in the drawing.
  • the actuation switch 4 On the front 3 of the housing 1, the actuation switch 4 is slidably mounted with an integrated long hair cutting system L. On the actuating switch 4, a shifting gate, not shown in the drawing, is formed with four latching positions "0,1,2,3", by means of which the respective switching position of the actuating switch 4 is determined.
  • the switch position "OFF" corresponds to the position "0" of the operating switch 4.
  • the actuation switch 4 is moved into the position "1".
  • the actuation switch 4 is moved to the position "2"
  • the long hair cutting system L integrated in the actuation switch is activated.
  • Figure 2 shows an exploded view of the shaving head 2 and the upper part of the housing 1 of a razor with partially broken side walls of the housing 1 and an arranged on the front 3, designed as a double switch actuating switch 4 consisting of the actuating part, not shown, and a long hair cutting system L.
  • To the Side walls 7 and 8 of the shaving head 2 are provided with bearing bolts by means of which the shaving head 2 is pivotably mounted in the bearing holes 5 and 6 provided around the pivot axis Z.
  • Identically designed swivel areas 10 are formed in the side walls 7 and 8.
  • the swivel area 10 formed in the side wall 8 is designed as a recess.
  • the side wall is designed such that it forms a lower cam track 13 as a control follower with a latch opening 14, wherein. the lateral stops 11, 12 limit the curved path 13.
  • FIG. 3 also shows a partial representation of the shaving apparatus 1 according to FIG. 1 with a swivel head control 30.
  • the control member is a step-shaped plunger 33, which is mounted in a side wall of the housing 1, which is not shown in FIG Shaver is slidably mounted.
  • the web part 17 is fixedly connected to, or integrated in, wall parts 23, 24 of the housing chassis 22 which run in parallel.
  • the cam track 13 is followed by a convex, further cam track or slideway 19 arranged at a distance from the cam track 13, against which a tappet head 34 arranged on the tappet 33 can be brought into abutment if the tappet 33 when the actuation switch 4 is adjusted by the switching position "0" has been adjusted to one of the switching positions "1" to "3".
  • the plunger 33 runs below the actuation switch 4 and extends through an opening 32 provided between the actuation switch 4 and the web part 17.
  • a hook 15 is arranged, which engages in a recess 20 provided on the actuating switch 4 and designed as an elongated hole opening, which has a reference to the direction of movement of the actuating switch 4 is open at the bottom or has such a large clearance that the plunger 33 is not influenced in its position when the actuating switch 4 is moved into the positions "1", "2" or "3".
  • a stop wall 21 of the recess 20 bears against the hook 15 and moves the plunger 33 into the "0" position.
  • a shaving head carrier 25 for pivotally receiving the shaving head 2, which is only pivotably received in the support arms 5, 6 shown in FIG.
  • a rectangular recess 26 designed as a tappet guide, in which the upper end of the tappet 33 is slidably received.
  • a step-shaped part 33 ′ of the ram is adjustably received in the space 35 between the shaving head support 25 and the web part 17.
  • a blind hole 27 is provided for receiving the spring 18, one end of which is supported against the inner end of the blind hole opening 27 and the other end of which is supported against the web part 17, so that the plunger 33 with its Ram head 34 is pressed against the slideway 19 when the operating switch 4 is in a position "1", "2" or "3".
  • the plunger head 34 is fixedly arranged at the upper end of the plunger 33, which is inserted in the "0" position of the actuating switch 4 into the latching opening 14 provided in the curved path 13 and thereby prevents the shaving head 2 can be pivoted about its pivot axis Z. Since the shaving head 2 is fixed in this position, it can be cleaned much more easily after shaving.
  • the actuation switch 4 is moved from the position "1" to the position "0".
  • the actuation switch 4 rests with its stop wall 21 against the hook 15 of the plunger 33 and moves it to the right with reference to the drawing.
  • the plunger head 34 is simultaneously displaced in the direction of the interior of the housing 1. If the shaving head 2 is in an inclined position, then the tappet head 34 slides along the surface of the cam track 13 and thereby forcibly swivels the shaving head 2 into its middle position shown in FIG. 3 and locks it in this position.
  • the spring 18 presses the plunger 33 in the direction of Shaving head 2, so that the plunger head 34 is guided out of its latching opening 14.
  • the plunger head 34 can protrude laterally at the upper end of the plunger 33, the outer end face of the plunger 34 being able to come into contact with the inner side wall 8 of the shaving head 2 when the recess 26 is open at the side .
  • the end of the plunger 33 which points in the direction of the shaving head 2 and the end of the plunger head 34 which points upward lies in the position “1” against the slideway 19 of the shaving head 2.
  • the plunger 33 can no longer be adjusted via the actuation switch 4 due to the correspondingly large recess 20, i.e. the connection between the actuating switch 4 and the plunger 33 is interrupted in the positions "1", "2" or "3".
  • the plunger 33 shown only on one side in FIG. 2, 3 can also be arranged on both sides of the shaving device.
  • the components of the control device for the shaving head 2 pivotally mounted about the pivot axis Z described in Figures 1 to 3 can be provided on one of the side walls of the shaver shown in a symmetrical arrangement to each other.
